TVS (Transient Voltage Suppressors) and varistors (Metal-Oxide Varistors) are components that are used by electrical engineers in order to protect electronics components and circuits from voltage spikes and transient voltages caused by power surges and static electricity emission. MOVs (Metal Oxide Varistors) are another form of similar technology that function in a similar way. The V680LA100CP is a popular combination of the two, providing Type II protection when exposed to overvoltages.

What is the V680LA100CP?

The V680LA100CP is a medium-power Varistor/TVS made by Littelfuse Inc. It is a bidirectional, low-pass, shielded, electromagnetic interference (EMI) filter-type TVS and varistor (MOV) combination. This combination allows engineers to quickly and easily add transient voltage protection to circuits with minimal added parts, cost, and space. The protection provided may also be supplemented with additional, external bilateral protection networks to ensure the best protection from transients and high voltages.

What are its Application Fields?

The V680LA100CP is mainly used in industrial electronic and automotive applications. Specifically, it is used to protect high-power, high-sensitivity systems and circuits where a robust transient protection solution is necessary. It is perfect for applications where primary systems (like electric motors) may be exposed to electrical overloads, sudden voltage jumps, or electrostatic discharges.

The V680LA100CP’s combination of varistor and TVS technology achieves both high-speed detection of overvoltage transients and fast response times that minimize breakdown and damage to other related components. Thanks to its shielded design and low-pass geometry, it is also suitable for preventing radiated emissions, which is an increasingly important aspect of modern electrical design.

How Does It Work?

The V680LA100CP works by detecting transients and overvoltages and then immediately ready to clamp them at a safe voltage amplitude. When the unit senses a voltage that is above its designated threshold, its internal MOVs divert the current, limiting the voltage and protecting the connected components. The unit’s low-pass filter design also helps to prevent radiated emissions.

When selecting the proper Varistor/TVS for a given design, it is important to measure and consider the operating voltage and transient energy of the application. The V680LA100CP is rated for an operating voltage of 100V and a transient energy of 400 Watts.

Conclusion

The V680LA100CP is a popular combination TVS and MOV that is perfect for industrial, automotive, and other electronic applications where robust transient protection is needed. It offers a fast response time and shielded design to ensure minimal damage to other components in case of an overvoltage or transient incident. Thanks to its low-pass filter design, it is also suitable for preventing radiated emissions.
